Specification of Letters Patent. Patgnted Jung 25 191 Application filed0ctober 10, 1914, Serial No. 866,109. Renewed May 17, 1918. Serial No.235,055.

To all whom it may concern:

Be it known that I, THEOPHILUS BROWN, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Mowers, of

. which thefollowing is a specification, referlar numerals indicateidentical parts- Figure 1 is" a plan view of a mower with the top of thegear case removed and the gearing shown in section.

Fig. 2 is an enlarged detail View showing the mounting of a portion ofthegearing.

Fig. 3 is an enlarged plan view ofthe member shown in elevation in Fig.2 and upon which a portion of the gearing is mounted.

Fig. 41 is an enlarged detail view and end elevation of the mechanismemployed to throw the gearing out of action, and

Fig. 5 is a plan view in art of Fig. 4.

My invention is applica le more particularly to the type of mowergearing shown and described in my pending application filed December 11,1913, Serial No. 806094, to which reference is made. i

The frame of the mower comprises a rear tubular portion 1, a forwardlyprojecting portion 2 to which a draft pole 3 is attached, and atubularportio-n 1 extending forwardly at right angles to the tubularportion 1. An axle 5 is journaled in the portion 1 and carriessupporting wheels 6 secured thereon with the usual type of pawl andratchet so that the axle will revolve with the forward motion of thewheels only. A gear case 7 is preferably integral with the mower frame.A cutter bar 8 shown in part, and of the ordinary type, is suppliedwitha knife bar 9 adapted to be actuated by a pitman 10 connected theretoand to a crank; 11, the latter being secured upon the forward end of acrank shaft 12 journaled in the tubular portion 4: of the frameya bevelpinion 13 is secured rigidly to the rear end of the crank and 17 and thebrackets 18 and 19 are dia-.

metrically opposite and are perforated to form bearings in which aremounted stub shafts 20, on each of which is a driving gear 21; each ofthe driving gears 21 has a pinion 22 revoluble therewith and in constantmesh with a gear 23 loosely mounted on the, axle 5. A bevel gear 21 isloosely mounted on the axle 5 and meshes with the bevel pinion 13 on thecrank shaft 12; preferably integral with the hub of the bevel gear 24 isa pinion 25 meshing with the gears 21. Within convenient reach from thedrivers seat 26 is a lever 27 pivotally supported on the mower frame.Slidably mounted in a bearing 28 on the mower frame and a hearing 29formed by an opening in a side of the gear case 7 is a bolt or stop 30adaptedto engage with any one of a series of circularly arrangedequidistant perforations a in the gear 23, and normally retained in suchon gagement by a coil spring 31 which exerts its pressure between thebearing 28 and a collar 32 rigidly secured to the bolt 30. A sliding camfaced member 33 is connected to the lever 27 and extends upwardly,having an elongated slot 34: through the upper end of which the bolt 30passes; the member 33 acts between the collar 32 and the bearing 29 sothat if the lever 27 is lifted the cam member 33 connected thereto willbe raised, the cam face thereof operating against the collar 32 andwithdrawing the bolt or stop 30 from engagement with a perforation inthe gear 23.

As shown in Fig. 1 the gearing is in proper engagement to transmit powerfrom the wheels 6 to the cutting mechanism upon starting the machine;the member 15 rigidly secured to the axle 5, between the gear 23 and thebevel gear 2 1 revolves therewith carrying the driving gears 21, and asthe gear 23 is free upon the axle 5 and held against movement by thebolt or stop 30, the driving gears 21 will be revolved through the pinpinion 13 the cutting mechani m is actuated by the revolution of thecrank shaft 12 upon 7 which. the bevel pinion 'is secured.

To prevent operation ofthe cutting mechanism when before its useisnecessary, or to stop it while in operation, I raise the lever 27 andconsequently the cam member 33 the latter operating between the face ofthe hearing 29 and the collar 32 rigidly secured on the bolt 30 causesthe latter to be withdrawn from engagement with one of the perforationsa in the gear 23; the gear 23 is now free to revolve on the axle 5, andwhile the member 15. revolves with the axle 5 the driving gears 21travel idly about the gear 23 and the pinion 25- conveying no powerthrough the, latter to actuate the cutting mechanism; it is obvious thatby lowering the lever 27 and the cam member 33 the bolt 30 underpressure of the coil spring 31 will again engage with the nearestperforation in the gear 23 and hold the latter securely against movementso that the power of the driving 1 gears 21, carried by the member 15which is V rigidly attached to the axle 5 between the gear 23 and thebevel gear 24:, will be employed upon the pinion 2 5 to drive the bevelgear 24 and through enmeshment of the latter with the bevel pinion 13 onthe crank shagt 12 the cutting mechanism will be oper ate By mountingthe member 15 between the gear 25 and the bevel gear 241 the strain ofthe work of the driving gears 21 and pinions 22, carried by the member15, is more evenly distributed, adding to the durability and efliciencyof the parts.

What I claim is 1. In a mower, the combination of an Y axle, groundwheels supported on the axle and adapted to rotate therewith in a for-Ward direction a reciprocating cutter, a train of power transmittingdevices in constant engagement'with each other and with the cutter andadapted to operate the latter by ground wheels supported on the axle andadapted to rotate therewith in a forward direction, areciprocatingcutter, a train of power transmitting devices in constantengagementiwith each other and with the cutter and adaptedto operate thelatter by P wertrom th gr nd Wheels wh n one f said devices is heldimmovable, said train comprising a bevel gear loosely mounted on theaxle'and permanently connected with the cutter, a second gear looselymounted on the axle, a member rotatable with the axle and rigidlysecured thereon between the bevel gear and the second gear,gearing'supported on said member and in constant ongagement with thebevel gear and second gear, and means to hold the second gear immovableduring operation of the cutter.

3. In a mower, the combination of an axle, ground wheels supported onthe axle and adapted to rotate therewith in a forward direction, areciprocating cutter, a train of power transmitting devices in constantengagementwith each other and with the cutter and adapted to operate thelatter by power from the ground wheels when one of said devices is heldimmovable, said train comprising a bevel gear loosely mounted on theaxle and permanently connected with the cutter, a second gear looselymounted on the axle, a member rotatable with the axle and rigidlysecured thereon between the bevel gear and the second'gear, gearingsupported on said member and in constant engagement with the bevel gearand second gear, means to hold the second gear immovable duringoperation of the cutter, said holding means being movable to release thesecond gear and check the operation of the cutter.

4. In a mower, the combination of an axle, ground wheels supported onthe axle and adapted to rotate therewith in a forward direction, areciprocating cutter, a train of power transmitting devices in constantengagement with each other and with the cutter and adapted to operatethe latter by power from the ground wheels when one of said devices isheld immovable, said train comprising a bevel gear loosely mounted onthe axle and permanently connected with the cutter, a second gearloosely mounted on the axle and having a series of circularly arrangedopenings, a member rotatable with the axle and rigidly secured thereonbetween the bevel gear and the second gear, gearing supported on saidmember and in constant engagement with the bevel gear and second gear,and a stop operable at will to engage with any one of said Openings tohold the second gear immovable during operation of the cutter, said stopbeing movable to release the second gear and check the operation of thecutter.

In testimony whereof I afiix my signature, in presence of two Witnesses.
